Abstract

A crash acceleration pulse control block for a vehicle. An auxiliary mounting unit capable of adjusting a crash contact area while serving as a bumper is installed at a front portion of a radiator lower member to obtain reliable initial crash acceleration of the vehicle. This is an important factor for determining the deployment of the airbag, even if the engine specification and the vehicle weight are changed, thereby accurately deploying an airbag according to the sensing operation of an airbag sensor when a vehicle accident occurs.

Claims

1. A crash acceleration pulse control block of a vehicle comprising an auxiliary mounting unit installed at a front portion of the vehicle to absorb impact energy applied to the vehicle when a vehicle accident occurs, wherein the auxiliary mounting unit adjusts a crash contact area of the vehicle, whereby an airbag may be accurately deployed based on reliable initial crash acceleration of the vehicle regardless of changes in engine specification and a vehicle weight.

2. The crash acceleration pulse control block as claimed in claim 1, wherein the auxiliary mounting unit includes a combination type block structure having a honeycomb shaped section.

3. The crash acceleration pulse control block as claimed in claim 2, in which plural blocks are provided in the combination type block structure in a number adjustable according to a vehicle specification so as to adjust a level of initial crash acceleration of the vehicle when the vehicle accident occurs.

4. The crash acceleration pulse control block as claimed in claim 1, wherein the auxiliary mounting unit includes an auxiliary bumper back beam in a form of a bar in which at least one of a sectional area of the bar is adjustable or a material for the bar is changeable according to a vehicle specification so as to adjust a level of initial crash acceleration of the vehicle when the vehicle accident occurs.
